Applications only control the kind of resources granted to them, and not which resources are granted to them. They, in turn, determine the use of these resources by users of the application through application security.

Open Web Application Security Project (OWASP) and Web Application Security Consortium (WASC) updates on the latest threats which impair web based applications. This aids developers, security testers and architects to focus on better design and mitigation strategy. OWASP Top 10 has become an industrial norm in assessing Web Applications.

OWASP, a leading application security industry authority, has acknowledged and prioritized the need for mobile application security, and recommended binary protection to mitigate the business and technical risks that mobile apps face. See Mobile Security Project - Top Ten Mobile Risks for Top Ten Mobile Risks based on new vulnerability statistics in the field of mobile applications.

The proportion of mobile devices providing open platform functionality is expected to continue to increase in future. The openness of these platforms offers significant opportunities to all parts of the mobile eco-system by delivering the ability for flexible program and service delivery options that may be installed, removed or refreshed multiple times in line with the user’s needs and requirements. However, with openness comes responsibility and unrestricted access to mobile resources and APIs by applications of unknown or untrusted origin could result in damage to the user, the device, the network or all of these, if not managed by suitable security architectures and network precautions. Application security is provided in some form on most open OS mobile devices (Symbian OS,[2] Microsoft, [3]BREW, etc.). Industry groups have also created recommendations including the GSM Association and Open Mobile Terminal Platform (OMTP).[4]

There are several strategies to enhance mobile application security including

Security testing techniques scour for vulnerabilities or security holes in applications. These vulnerabilities leave applications open to exploitation. Ideally, security testing is implemented throughout the entire software development life cycle (SDLC) so that vulnerabilities may be addressed in a timely and thorough manner. Unfortunately, testing is often conducted as an afterthought at the end of the development cycle.

Vulnerability scanners, and more specifically web application scanners, otherwise known as penetration testing tools (i.e. ethical hacking tools) have been historically used by security organizations within corporations and security consultants to automate the security testing of http request/responses; however, this is not a substitute for the need for actual source code review. Physical code reviews of an application's source code can be accomplished manually or in an automated fashion. Given the common size of individual programs (often 500,000 lines of code or more), the human brain can not execute a comprehensive data flow analysis needed in order to completely check all circuitous paths of an application program to find vulnerability points. The human brain is suited more for filtering, interrupting and reporting the outputs of automated source code analysis tools available commercially versus trying to trace every possible path through a compiled code base to find the root cause level vulnerabilities.

According to Gartner Research,[16] "...next-generation modern Web and mobile applications requires a combination of SAST and DAST techniques, and new interactive application security testing (IAST) approaches have emerged that combine static and dynamic techniques to improve testing...", including: Contrast™[17] and Quotium Technologies.[18] Because IAST combines SAST and DAST techniques, the results are highly actionable, can be linked to the specific line of code, and can be recorded for replay later for developers.

Banking and large E-Commerce corporations have been the very early adopter customer profile for these types of tools. It is commonly held within these firms that both Black Box testing and White Box testing tools are needed in the pursuit of application security. Typically sited, Black Box testing (meaning Penetration Testing tools) are ethical hacking tools used to attack the application surface to expose vulnerabilities suspended within the source code hierarchy. Penetration testing tools are executed on the already deployed application. White Box testing (meaning Source Code Analysis tools) are used by either the application security groups or application development groups. Typically introduced into a company through the application security organization, the White Box tools complement the Black Box testing tools in that they give specific visibility into the specific root vulnerabilities within the source code in advance of the source code being deployed. Vulnerabilities identified with White Box testing and Black Box testing are typically in accordance with the OWASP taxonomy for software coding errors. White Box testing vendors have recently introduced dynamic versions of their source code analysis methods; which operates on deployed applications. Given that the White Box testing tools have dynamic versions similar to the Black Box testing tools, both tools can be correlated in the same software error detection paradigm ensuring full application protection to the client company.

The advances in professional Malware targeted at the Internet customers of online organizations has seen a change in Web application design requirements since 2007. It is generally assumed that a sizable percentage of Internet users will be compromised through malware and that any data coming from their infected host may be tainted. Therefore application security has begun to manifest more advanced anti-fraud and heuristic detection systems in the back-office, rather than within the client-side or Web server code.[19]
